OK so it's kind of two different things but both pertain to the installation of the Membership Plugin.
1. When viewing the site with Internet Explorer, on the home page my widgets disappear. They were OK prior to the installation. Any ideas? Is it something to do with some permission level? And if so why doesn't it do it in Firefox. Again both worked fine prior to installation of Membership.
Second issue. when I'm logged in (admin of course) and I preview the page with the [free] shortcode, it shows up. I can see it in the post. When I view the post not as a member it displays properly. I am not sure what's happening.
